Two equal electric currents are flowing perpendicular to each other as shown in the figure. 
and 
are perpendicular to each other and symmetrically placed with respect to the currents. Where do we expect the resultant magnetic field to be zero?
A
On 
B
On 
C
On both 
and 
and
D
On both 
and 
and
Text Solution
Verified by ExpertsThe correct answer is:
B
The direction of the magnetic field, due to current, is given by the right‐hand rule. At axis 
, the components of magnetic field will cancel each other and the resultant magnetic field will be zero.
